Na Hoku 3 Catamaran (Waikiki Beach)

Departing in front of Duke’s Restaurant, the 49-passenger catamaran runs on a decidedly social tempo. An energetic crew keeps drinks poured and music going, setting an easy stage for sing-alongs and casual conversation on the water. Outings are relatively brief, and the environment changes with the timing: all ages are welcome aboard, but evening and weekend runs frequently lean into a bar-motivated crowd or party atmosphere.
